Overall cleanup, simplification and automation pass

[kaosat-dev]

This repo has grown quite a bit out of hand & releases are growing ever more complex

• [x] too many partially redundant examples (ie basic vs basic-wasm) etc , and over 15 examples at this stage, this needs to be trimmed down
• [ ] no release automation, which makes for some very time consuming release process: ie
  • [ ] testing out every Blender file auto export with EVERY example, running those examples should be automated
  • [x] add tests to bevy_components
  • [x] add tests to gltf_auto_export
  • [ ] integrate with CI
• [x] except for bevy_gltf_components (not even sure for that one), change all example Blend files to use components created with bevy_components (ie metadata & co)
